Computer simulation of femtosecond pulsed laser ablation of aluminium and copper

Abstract

In this paper a mathematical model for laser ablation of metals by femtosecond laser pulses is developed, based on two-temperature model with hydrodynamic equations and wide-range equation of state for metals. The simulation results for aluminium and copper are compared with experimental data for ablation depth at different laser fluence and duration of pulses. A good agreement for both metals with the results of simulation and the experiment is received.
